there seems to be a bug in your commands column and it's made worse when loading/saving grid layouts.

When i load a page with this grid column definition, 

.Groupable()
                    .Columns(columns =>
                    {
                        columns.Command(cmd => cmd.Custom("Undelete")
                            .Click("undelete"))
                            .Width(60);

when you inspect the grid, the grid internally shows two classes for the command cell:

attributes: {class: 'k-command-cell k-command-cell'}

now, if i apply a grid layout, the problem gets worse.  This sample code will cause the dom to end up with multiple k-command-cell classes on the grid's td element.

$("#UndeleteGrid").data("kendoGrid").setOptions($("#UndeleteGrid").data("kendoGrid").getOptions())

<td class="k-command-cell k-command-cell k-command-cell k-command-cell k-command-cell k-command-cell k-command-cell k-command-cell k-command-cell" role="gridcell"><a role="button" class="k-button k-grid-Undelete" href="#" title="Undelete"><span class="k-icon k-i-undo"></span></a></td>

Describe the bug
Column headers do not resize properly in IE11 when scrollable is set to false. Regression introduced in 2021.3.914.

The column headers are squished to the left side.

Expected behavior
Columns headers must have the same width as the respective columns.

Workaround:

.k-ie .k-grid-header {
  display: table-header-group;
}

When using the Grid Endless Scrolling, is there a way to prevent the existing records from momentarily disappearing as the spinner appears?

Using endless scrolling on a large grid (full screen), the users eye tracks down the list as the mousewheel is turned. At the moment the next page is fetched, the view of the data is disrupted as the spinner appears and the data disappears. This can be quite jarring to the senses when browsing for a specific record in the list.

On a small grid such as that on the example page (https://demos.telerik.com/kendo-ui/grid/endless-scrolling-remote) it isn't quite as jarring on the senses, but with a large grid with many columns and rows, it can be very off-putting.

Ideally, if the existing records can remain opaquely visible in the background under the spinner whilst the next page of data is being retrieved, it would produce a much cleaner user experience.

Hi Team,

Bug Report

The Kendo UI Grid's toolbar with a template is not persisted when the Grid is loaded using setOptions. 

Reproduction of the problem

With a toolbar containing a template with server tags, the toolbar content will disappear.

Expected Behavior

The Grid should retain the toolbar with the HTML contained when using setOptions.

Environment

Kendo UI version: 2022.2.510
jQuery version: all
Browser: all

Thanks!

Bug report

Reproduction of the problem

Dojo example: https://dojo.telerik.com/InUYAheR/4
Drag and drop a row from Grid2 to Grid1 by following the steps below:

1. Click and hold down the mouse button within a Grid2 row, just before its ID value or a little after it.
2. Drag the row to Grid1 and drop it over row 3 or row 4.

Current behavior

Grid1's first row values get updated, instead of the drop target row values. This is because e.target in the DropTarget's "drop" event does not return the actual target you drop over.
If you click and drag in the middle of the Grid2 row, drag it and drop it over a row in Grid1, the drag and drop functionality works as expected: e.target returns the correct target.

Expected/desired behavior

e.target should consistently return the target you drop over, regardless of where in the dragged row you have clicked.

Bug report

Reproduction of the problem

Reproducible in the demos: https://demos.telerik.com/aspnet-mvc/grid/persist-state

1. Inspect the rendering of the "Contact Name" header in the MVC and Kendo UI for jQuery demos.

Current behavior

The difference in the rendering is shown below. In the Kendo UI Grid's Html, there is a span with class "k-cell-inner" that wraps the ".k-link" span, whereas in the MVC Grid, only an anchor is rendered.

Kendo UI:

<th scope="col" role="columnheader" data-field="ContactName" aria-haspopup="true" rowspan="1" data-title="Contact Name" aria-label="Contact Name Press ctrl + space to group" data-index="0" id="a44eadd9-62c6-4154-9735-4351a9cb5064" class="k-header k-filterable" data-role="columnsorter" style="touch-action: none;">
  <span class="k-cell-inner">
    <span class="k-link">
      <span class="k-column-title">Contact Name</span>
    </span>
    <a class="k-header-column-menu" href="#" title="Contact Name edit column settings" aria-label="Contact Name edit column settings" tabindex="-1">
      <span class="k-icon k-i-more-vertical"></span>
    </a>
  </span>
</th>

MVC:

<th class="k-header k-filterable" data-field="ContactName" data-index="0" data-title="Contact Name" id="f28afe50-210a-474d-9943-113f6bd4ad15" scope="col" data-role="columnsorter" style="touch-action: none;">
  <a class="k-link" href="/aspnet-mvc/grid/persiststate_customers_read?grid-sort=ContactName-asc">Contact Name</a>
  <a class="k-header-column-menu" href="#" title="Contact Name edit column settings" aria-label="Contact Name edit column settings" tabindex="-1">
    <span class="k-icon k-i-more-vertical"></span>
  </a>
</th>

Expected/desired behavior

Identical rendering.

Bug report

When the Grid AutoBind() configuration is set to false, the Grid is rendering an empty cell in the row element with class .k-no-data. (Image.png)

Reproduction of the problem

Set AutoBind configuration of Telerik UI for Asp.Net MVC Grid to 'false'. The Grid is rendered correctly except for the empty row and the empty cell in the table body.

Current behavior

An empty row with one empty cell is rendered.

Expected/desired behavior

The tbody element should be empty.

Environment

• Kendo UI version: 2022.2.621
• Browser: [all]

Bug report

Reproduction of the problem

1. Set up a Grid to use server binding
2. Add a custom command:

columns.Command(command => command.Custom("View Email"))
	.Title("Body")
	.Width(150);

Current behavior

When the Grid is configured to use server binding, it will render an anchor element. If remote binding is used, the Grid will correctly render a button element.

Expected/desired behavior

Consistency in the rendering. A button element should be rendered, regardless of using server or remote binding.

Environment

Not sure if this is already in the works but when building mvc grids it would be helpful to have the ability to prevent a column from getting too big when the screen size is larger than the grid needs. Right now if columns are turned off and there is more space for the unlocked columns, they expand to fill the page which is normally fine but in some instances it looks silly to have a column for example that you would enter a 2 digit number in to be 300 plus px wide.

Bug report

When the scrollable option is disabled, on resizing the browser window by making it more narrow, at certain point the columns stop resizing and the whole table goes out of the right border of the Grid. Reproducible with the SASS and LESS themes.

Reproduction of the problem

Dojo example: https://dojo.telerik.com/ItIrEzEY/3

1. Either resize the right pane or use Fullscreen and resize the browser window and make it narrower.

Current behavior

The table goes out of wrapping element (.k-grid).

Expected/desired behavior

The columns resize and the table remains within the borders of the Grid.

Environment

• Kendo UI version: 2023.1.117

Bug report

The attributes handler overload does not get executed when the column is initially marked as hidden.

Reproduction of the problem

1. Open the following dojo.
2. Change the hidden property of the ContactTitle field to true.

Current behavior

The attributes handler is not executed when the column is hidden.

Expected/desired behavior

The attributes handler should be executed when the column is hidden.

Bug report

Not reproducible with the UI for ASP.NET Core Grid helper.

Reproduction of the problem

1. Set the Total option of the DataSource in a Grid:

.DataSource(dataSource => dataSource
    .Ajax()
    .PageSize(15)
    .Read(read => read.Action("Orders_Read", "Grid"))
    .Total(50)
)

2. Compare the rendering of the pager "next page" and "last page" buttons with the Total option set and without it.

Current behavior

The "next page" and "last page" buttons in the Grid's pager are rendered as anchor Html elements, when Total is set in the DataSource. When it is not set, the buttons are rendered as button Html elements.

Expected/desired behavior

The rendering of the pager buttons should be consistent and they should render as button Html elements.

Environment

• Kendo UI version: 2023.1.425

Bug report

Prerequisites: reordering a non-locked column before a locked column. There could be one or more locked columns.
This behavior appeared in v2021.3.1207.

Reproduction of the problem

Dojo example: https://dojo.telerik.com/UhExAXIv/5

1. Click, hold and slowly drag the header of the OrderDate column over the locked ID column.
2. Attempt to reorder the OrderDate column before the ID column.

Current behavior

The reorder hint appears only when you hover the left border of the ID cell. This makes dropping the header at the right spot difficult, since you have to be very precise and if you are too fast, you have to re-adjust the mouse cursor position right on top of the left border of the cell.

Expected/desired behavior

The reorder hint should appear when mouse cursor enters the boundaries of the target cell. For example, slowly drag ShipCity before ShipCountry. Note how the reorder hint appears once you enter the boundaries of the ShipCountry cell and you don't have to drag all the way to ShipCountry's left border.

Bug report

Reproducible in MVC with a custom toolbar tool that has a ClientTemplate.

Reproduction of the problem

1. Configure the Grid for incell editing and a custom command with a template to its toolbar configuration

@(Html.Kendo().Grid<TelerikMvcApp2.Models.OrderViewModel>()
    .Name("grid")
    .Columns(columns =>
    {
        columns.Bound(p => p.OrderID).Filterable(false);
        columns.Bound(p => p.Freight);
        columns.Bound(p => p.OrderDate).Format("{0:MM/dd/yyyy}");
        columns.Bound(p => p.ShipName);
        columns.Bound(p => p.ShipCity);
    })
    .ToolBar(toolbar =>
    {
        toolbar.Save();
        toolbar.Spacer();
        toolbar.Custom().ClientTemplate("<span>test</span>");
    })
    .Pageable()
    .Sortable()
    .Scrollable()
    .Filterable()
    .HtmlAttributes(new { style = "height:550px;" })
    .Editable(editable => editable.Mode(GridEditMode.InCell))
    .DataSource(dataSource => dataSource
        .Ajax()

        .Create("Orders_Create", "Grid")
        .Update("Orders_Update", "Grid")
    )
)

Current behavior

Duplication of the "Cancel" button.

Expected/desired behavior

A single "Cancel" button is rendered in the toolbar.

### Bug report

When the Grid uses an external DataSource, the aggregates are undefined within the ClientGroupFooterTemplate().

### Reproduction of the problem

Use the following REPL sample that demonstrates the issue:

https://netcorerepl.telerik.com/mIkyQnvB382bsiFt24

1. Group the Grid by the "Freight" column.

2. An error is thrown in the browser console: "Uncaught ReferenceError: sum is not defined".

3. The aggregates=["sum"] is missing in the column options in the Grid initialization script;

"columns":[{"title":"Order ID","field":"OrderID","filterable":false,"encoded":true},{"title":"Freight","groupFooterTemplate":"Sum: #=sum#","field":"Freight","filterable":{"messages":{"title":"Show items with value that"},"checkAll":false},"encoded":true},{"title":"Ship City","width":"150px","field":"ShipCity","filterable":{"messages":{"title":"Show items with value that"},"checkAll":false},"encoded":true}]

When the DataSource is defined within the Grid configuration, the aggregate is displayed as expected.

### Expected/desired behavior

The "sum" aggregate must be displayed within the group footer template of the column when the Grid is grouped.

### Workaround

Define the DataSource in the Grid configuration or update the Grid settings by using the setOptions() method when the page is loaded:

<script>
    $(document).ready(function () {
        var grid = $("#grid").data("kendoGrid");
        if (grid) {
            let gridColumns = grid.columns;
            if (!gridColumns[1].aggregates) { // update [1] with the index of the column that has a group footer template. For example, "1" is the 2nd Grid column
                gridColumns[1].aggregates = ["sum"];
                grid.setOptions({ columns: gridColumns });
            }
        }
    });
</script>
